To allow the USB devices to be read and written by a non-privileged user, create a file called  ''/etc/udev/rules.d/51-garmin.rules'' with the following contents: 
{{{SYSFS{idVendor}=="091e", SYSFS{idProduct}=="0003", MODE="666"}}}

!! Firefox Auto Hide Toolbar in Fullscreen Mode

When you press F11 and go fullscreen, the toolbar auto hides and appear upon mouse over.This key changes the function of auto hide part.

* Key : browser.fullscreen.autohide
* Default Value : True (Always auto hide)
* Modified Value : False (always show the toolbar)
!! Improvements

Things that have improved with this release:

* boots much faster
* logon screen looks much better
* less energy consumption probably, at least the fan isn't blowing all the time
* wireless driver now also supports power-saving
* googleearth now properly displays stall letters 
* "better" animations for actions (network connect/disconnect changing screen brightness)

!! HP 6830s specifics

My latest laptop requires some extra tweaks :

! Sound

Add the following line to /etc/modprobe.d/alsa-base.conf:
{{{
options snd-hda-intel model=laptop enable=1 index=0
}}}

! Video driver

Install the native ATI/AMD video driver if you want 3D effects. If you don't need that, the default driver is fine too.

! Wireless driver

This one works magnificently out of the box:

! fan control

First disable the BIOS option "Fan Always on while on AC Power".

But after that you still see the fan going on fairly loud at 47 degrees Celsius and turning off at 42 (if the environment is not too warm).
To change this behavior you can patch the dsdt tables:

__Patching DSDT tables__

The following resources were helpful:
* [http://ubuntuforums.org/showthread.php?t=1036051]
* [http://milksnot.com/joomla/windows-xp/acpi-hacking-silencing-your-laptop]

I followed the following procedure (mainly as described in the first link above):

* disassemble the current dsdt table
{{{
mkdir dsdt
cd dsdt
cp /proc/acpi/dsdt .
# disassemble it
iasl -d dsdt
# save the original
cp dsdt.dsl dsdt-orig.dsl
# now first edit the dsdt.dsl file (see below) and then recompile:
iasl -tc dsdt.dsl
#
# update initial ramdisk
#
cp dsdt.aml /etc/initramfs-tools/DSDT.aml
VERSION=`uname -r`
update-initramfs -u -k $VERSION
#
#  then reboot
}}}

__DSDT Patch__

These numbers are hexadecimal and seem to indicate the percentage of fanspeed, so 0x64 is 100% fan speed. I don't know if temperature thresholds are included, I don't think so.

!! Font settings

Thanks to [http://blog.xam.dk/archives/81-Making-Eclipse-look-good-on-Linux.html]

{{{
After they are installed I ran gnome-font-properties and used the following settings:

Application/Document/Desktop font: Liberation Sans, size 8
Window title font: Liberation Sans Bold, size 10
Fixed with font: Liberation Mono, 10

Font rendering: Best contrast (the others left weird artifacts, but mostly up to taste here I think)

Under details:
Resolution: 99 dpi (to avoid the letters to get too close, need at least 1 px between them 
Smoothing: Grayscale

Hinting: Full 

Depending on your Eclipse font settings the above will be enough, 
but if you already have tweaked some settings remember to check your Font settings under Eclipse preferences 
and verify that you are actually using the System default or the Liberated fonts to get the smoother more compact look.

* change /etc/init.d/rc : ''CONCURRENCY=shell'' =>  take advantage of dual-core processors
* reprofile the boot sequence to get a good readahead file  (/etc/readahead folder)
